英语语法：that引导原因状语从句的四种情况

第⼀种情况

连词that很少⽤来引导原因状语从句，但在某些表⽰情感的不及物动词之后，that 分句说明这种情感产⽣的原因，因⽽可以看作原因状语分句。

例如：

I rejoice that you are coming home.你要回家我很⾼兴。I grieve that he has lost his dear child.他失去了孩⼦我很悲伤。

第⼆种情况

在以表⽰情感状态的形容词为主语补语的SVC结构中，that-分句也可以看作原因状语分句，表⽰这种感情所产⽣的原因。

例如：

I am pleased that you have decided to come.I am sorry (that) I broke your pen.

I am ashamed that you should be so cowardly.I was surprised that he disagreed.

第三种情况

在not that… but that…结构中，that=because，从⽽这种that-分句也是原因状语。I haven’t finished writing the report yet, not that I dislike the work, but that I have not time.

He always travelled third-class, not that he was so miserly,but that he wanted to go side by side with ordinary people.

第四种情况

在下列结构中，that=as，它所引导的分句有时表⽰原因，有时表⽰让步：Coward that he was, he ran away as soon as the enemy attacked. (表原因)Coward that he was, he ran forward at the signal to attack（表让步）
